On the Wii, things are looking decidedly different: WebM is the primary video format used in the app, and codecs like H.263 are only used as a fall-back option. This makes the app “the largest deployment of WebM video in the world today,” according to a YouTube spokesperson.

YouTube has been aggressively working on rolling out native and content-centric app experiences on as many platforms as possible, with an app for the video site now being available on over 400 million devices. Part of this has to do with the fact that it’s easier to monetize content in a native app experience. But going native also allows YouTube to add other functionality, like the AirPlay-like experience it rolled out on Google TV earlier this week, which the company intends to bring to other platforms and devices in the coming months.
